Description & Operation (Instrument Panel Cluster): Speedometer

The IPC displays the vehicle speed based on the information from the PCM. The PCM converts the data from the vehicle speed sensor to a 4000 pulses/mile signal. The IPC uses the vehicle speed signal circuit from the PCM in order to calculate the vehicle speed. The speedometer defaults to 0 MPH (0 KM/H) if a malfunction in the vehicle speed signal circuit exists. The speedometer will display either miles or kilometers as set by the ENG/MET button on the driver information center (DIC).

On vehicles equipped with the analog cluster, speedometer digital display configuration and back lighting can be changed by using the DSPL MODE button, located between trip odometer and ENG/MET button. The speedometer can be configured with a digital image in addition to analog image.
